The "atdt<number>^M" part can be automated by using -p telco!ispname
if you trust telco (and if your /lib/ndb/local has a line like
sys=ispname telco=555-1234).

The further handshaking (if you need a login script for an isp
which doesn't support CHAP or PAP) can be automated by persuading
ip/ppp to call a command, in the manner of the -c option of con(1),
instead of reading user input.  You can use rc as a scripting language -
below is my quickly thrown together script for logging into Compuserve
(where 'cread -t N C' is a variant of read(1) which copies from stdin
to stdout until either a character C is encountered or N seconds elapse).

I could post the source for cread, and the change to ppp to call command
scripts, but they're both pretty obvious.

It does.  However, it doesn't do the reset of the handshake.  There are
too many danged ways to attach to an ISP.  I have to dial the number,
type a user name, an exncrypted time, and then the string ppp, each
to a prompt and with no type ahead allowed.  My mom's ISP goes through
a similar but different dance.  My girl friend's uses PAP without
a dance.

I started writing a scripting language for it and got distracted by
looking at the Unix one, expect(?).  I'll get back to it eventually or someone
else should do it.  Then we could have standard scripts for different
ISP's and avoid a lot of typing.

[9fans] connecting to ISP with PAP?

[William Staniewicz]

With the help of:
nigel@9fs.org presotto@plan9.bell-labs.com miller@hamnavoe.demon.co.uk
I believe I have managed to be able to log on to my ISP.
This involved applying the PAP patch to PPP and using the script:
ip/ppp -s $host:$pass -uf -p '#t/eia1' -b115200
then,
atdt0,5303333^M

When I test the "log on" status with,
term% ip/ping 195.121.1.34 there  seems to be a connection.

What I have not done yet is provide for my
ISPs Domain Name Servers dns=195.121.1.34 and
My ISPs server uses DYNAMIC IP numbers.

I suspect I will need to put that information
the ipconfig command.

I hope I have documented this well enough so others can apply
it to their own situation. I know the archives have been useful to me
as well as the feedback from my postings.

Here are my results as I follow your advise posted above:

Furthermore, if I type in the command...

According to the packing slip, it is a:

Re: [9fans] connecting to ISP with PAP?

[presotto]

Try it without telco at all.  Just dial the number through ppp.  We
can cross the telco bridge when we've got real connections.

To dial through ppp:

	ip/ppp -fP -m 1500 -p /dev/eia1 -s $host:$pass

and when it prompts you type

	atdt0,5303333^M

where '^M' is the ctrl key plus the m key.  The
'at' interface needs real carriage returns.

After it's connected, just type
	^D

If that works, we can go on to debugging telco
or, better yet, ignore it completely.

[9fans] connecting to ISP with PAP?

[William Staniewicz]

Here is what I have done:

1.  Copied ppp.bod to /sys/src/cmd/ip/ppp
2.  % disk/kfscmd allow
3.  % chmod 777 ppp.bod
4.  % ppp.bod
        (Here, some info was provided telling me to use
        -X to extract.)
5.  % ppp.bod -X
        973778772/ppp.c: /sys/src/cmd/ip/ppp/ppp.c is not
        the original distribution file
        (A directory was created but not sure if this comment
         is telling me the patch was applied successfully.)
6.  Into /rc/bin/termrc I put:
    host=myloginname
    pass=myISPpassword
7.  I added the IP numbers of my ISPs Domain Name Servers
    so that my /lib/ndb/local looks like:
    database=
            file=/lib/ndb/local
            file=/lib/ndb/common
    dns=195.121.1.34
8.  My ISPs server uses DYNAMIC IP numbers.
9.  % telco /dev/eia1
    (Is there a way to set this up at boot time?)
    (There is maybe a 5 sec. pause at this time then
     the prompt is displayed.)
10. % ip/ppp -fP -m 1500 -p telco!0,5303333 -s $host:$pass
    (Modem dials out, about a min later I hear it disconnect
     and the following is displayed.)
    *s*: *s*: *r*
    telco 181: suicide: sys: trap: fault read addr=0x24448900
    pc=0x24448900
    (The process stops here...)

I think I am close to a solution on this. I appreciate the
help I have been given to get to this point. Can anyone
suggest what to do next?

You can type them directly in the command line, or set them as
shell (rc) variables if you are calling ip/ppp in a script.

I don't know of a simple step-by-step guide for this; you will want
to look at ndb(6), listen(8), mail(1) and smtpd(6).

.bods are "bundles of diffs", or a form of patch used in 2nd edition Plan 9. The file
should be an rc script. Just run it to get a small amount of help on the arguments

Re: [9fans] connecting to ISP with PAP?

[Richard Miller]

Oops .. after applying the PAP update to /sys/src/cmd/ip/ppp, you might want to
change the following line:

	netlog("PPP: pap: send authreq %d %s %s\n", c->id, ppp->chapname, ppp->secret);
to
	netlog("PPP: pap: send authreq %d %s %s\n", c->id, ppp->chapname, "****");


to prevent your ISP password from appearing in debugging output.

Attached is an update to /sys/src/cmd/ip/ppp (14 Oct version) to support
PAP authentication.  Note that although PAP is less secure than CHAP
(password is transmitted in cleartext), the specification says that
servers which provide both must offer CHAP first.

The command I use to connect to Demon UK is:

% ip/ppp -fP -m 1500 -p telco!0845-212-0666 -s $host:$pass

[9fans] connecting to ISP with PAP?

[William Staniewicz]

I know CHAP is supported, but is it possible to
connect to my ISP with PAP?

I have read the manuals for ppp and con and telco
but cant seem to get logged on successfully.

I've tried,

	telco /dev/eia1
	con -l telco!5551212

		(this gets me dialed in, but not
		 logged on)

Also tried,

	ip/ppp -p /dev/eia1 -s myusername:password -t atdt5551212

		(The only thing this does is produce a clicking
		 sound as my modem responds. There is no dialtone
		 or anything else that follows)
